Research Interests:

My research deals with visual perception and cognition. Currently, projects in my lab focus on the roles of vision in reading, object recognition, and spatial navigation. In all of these areas, I have a special interest in the problems encountered by people with low vision.

My lab has been widely recognized for applying the principles and methods of basic visual science to explain the difficulties encountered by people with low vision. One practical outcome of our research is the development of the MNREAD Acuity Chart, designed for use in normal and low vision.

Other areas of my research include studies of binocular vision (including stereopsis) and contrast coding.
